Find the Value of X in simplest radical form and Find the measure of angle A.
Answers
Answer:
A = 30°
x = 9·√3
Step-by-step explanation:
Part A
In the drawing, we are given;
The radius of the circle with center at point S = SA = 18
ΔAHA is a right triangle
One of the leg length of ΔASH = 9
The length of the hypotenuse side of ΔASH, AS = 18 The radius of the circle with center at the point 'S'
By Pythagoras's theorem, the length of the (radius) side, AS = √(SH² + AH²)
∴ AH = √(AS² - SH²)
AH = √(18² - 9²) = √(243) = 9·√3
AH = 9·√3
By circle theorem, SH bisects the line AH extended to the circumference of the circle
SH bisects the line with length AH + x
∴ AH = x
x = AH = 9·√3
x = 9·√3
Part B
By trigonometric ratios, we have;
[tex]sin\angle A = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
[tex]\therefore sin\angle A = \dfrac{9}{18} = \dfrac{1}{2}[/tex]
∠A = arcsine (1/2) = 30°
Angle A = 30°

which of the following decimal has highest value is a 0.5 b 0.12 c 0.17 d 0.8
Answers
Answer:
d 80 cents or 0.8
Step-by-step explanation:
Change them all to money. Then look at it again.
0.5 = 50 cents
0.12 = 12 cents
0.17 = 17 cents
0.8 = 80 cents.
You get each of them by starting with a dollar. A dollar has 100 cents.
So 0.5 of a dollar is 1/2 a dollar.
1/2 a dollar is 0.5 * 100 = 50 cents
0.17 * 100 = 17 cents
0.12 * 100 = 12 cents
0.8 * 100 = 80 cents
The largest one is 8
Answer d) 0.8
Step-by-step explanation: Here is a tip, when you see a decimal like 0.5 compared to a bigger looking one like 0.12 add a 0 to the end. It will still have the same value and you won't be as confused.
0.80> 0.50> 0.17> 0.12

Find an equation for the line below
Answers
Given the definitions of f(x) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x^2 + 6x – 8
I don’t need work I am just looking for the answer !
Answers
gf(x) = g(x^-1) = x^2 + 6x - 8
f(x) = 2x - 10
gf(x) = 6 ( 2x - 10) - 8
gf(x) = 12x- 60 - 8
gf(x) = 12x -68
gf(5) = gf(x) = 12x - 68
gf(5) = 12(5) - 68
gf(5) = 60 - 68
gf(5) = -8

Sunitha solved the problem as shown. A circle with radius 20 feet. A larger circle is 4 feet larger than the smaller circle. Radius = 24 feet. Circumference = 24 pi. What was her error? She should have used 12 in the formula, not 24. She forgot to multiply the radius by 2 in the formula. She did not add the additional fence length to the pool’s radius.

Answers
Complete Question
Two geometrically similar jugs have volumes of 1000 cm³and 512 cm³.They have circular bases. The diameter of the base of the larger jug is 9 cm.
Calculate the diameter of the smaller jug.
Answer:
7.2 cm
Step-by-step explanation:
To solve the above question,we have the proportion
Smaller volume/ Larger volume = (Smaller diameter/ Larger diameter)³
We are to find the smaller diameter
Hence our formula is give as
Cube root(Smaller volume/ Larger volume)= Smaller diameter/ Larger diameter
=cube root( 512/1000) = x/9
= 8/10 = x/9
Cross Multiply
10x = 8 × 9
10x = 72
x = 72/10
x = 7.2cm
Therefore, the diameter of the second jug is 7.2 cm

In order to this proceed with division,
Since we know that,
When the numerator is equal to or more than the denominator, the fraction is said to be inappropriate. It always has a value of one or higher. Since mixed fractions are simpler to understand, improper fractions are typically expressed in simplified mixed number form.
